medium setting
The cooling unit’s performance is influenced by ambient temperatures.
Please select the medium setting for ambient temperatures between
+15°C and +25°C. The unit operates within its optimum performance range.
5.3
DOMETIC refrigerators work according to the absorption principle.
Due to physical reasons, an absorption system responds slowly to changes
made on the thermostat controller, or a loss in cooling through opening the
door, or storing food. The devices fulfill the cooling performance require-
ments of the Climatic Class SN acc. to EN/ISO 7371 in the temperature range
of +10°C to 32°C ambient temperature.
5.3.1
5.3.2
Freezer compartment
Do not keep carbonated drinks in the freezer.
The freezer compartment is suitable for making ice cubes and for short-term
storage of frozen food. It is not suitable as a means of freezing foods.
When ambient temperatures are lower than +10°C an even regulation of freezer
temperature cannot be guaranteed, if the refrigerator is exposed to these tem-
peratures for a long period of time. This can cause the temperature in the free-
zer to rise and the stored goods to defrost.
WARNING
Storing food
General advices
Switch the refrigerator on approx. 12 hours before filling it.
Always store pre-cooled foods in the refrigerator. Make sure that the food is well
cooled when it is bought and also when transporting it. Use insulated cooling bags.
When taking food out of the refrigerator only open the refrigerator door very briefly.
Foods must be packed - best of all in closed containers - and stored separately from
each other.
Allow foods that have been warmed up to cool down before storing.
Products that could emit volatile, flammable gases must not be stored in the refrige-
rator.
Store quickly perishable foods directly next to the cooling fins.
The refrigerator must not be exposed to direct sunlight. Please bear in mind that the
tem- perature inside a closed vehicle increases sharply if exposed to sunlight and
that this can reduce the efficiency of the refrigerator..
The air around the cooling unit MUST be able to circulate freely without any hindran-
ce (see also section 6.3 "Ventilation and air extraction") .
10
Making ice cubes
Ice cubes are best frozen overnight. At night, the refrigerator has less work to do and
the unit has more reserves.
Defrosting
As time goes by, frost builds up on the fins.
When the layer of frost is about 3mm thick, the refrigerator should be defrosted.
1. Switch off the refrigerator, as described in Section 5.8 - "Switching off".
2. Remove the ice cube tray and food.
3. Leave the refrigerator door open.
4. After defrosting (freezer compartment and fins free of frost), wipe the cabinet dry
with a cloth.
5. Use a cloth to mop up the water from the freezer compartment.
6. Switch the refrigerator back on again.
The layer of ice must never be removed forcibly, nor may defrosting be
accelerated using a heat source.
Note:
Water thawing in the main compartment of the refrigerator runs into an appropriate
container at the back of the refrigerator. From there, the water evaporates.

6.1.2
It is also possible to perform ventilation of the refrigerator via an aperture in the floor
and a roof ventilation (see fig. 3). A flue
has to be provided between the top edge
of the refrigerator and the roof ventilation
which directs the hot air and the exhausts
straight to the air vent in the roof.
The opening in the floor must have a cross
section of at least 250cm². Protect the
opening, e.g. with a baffle plate and a net,
to prevent dirt from entering the gas bur-
ner. Compared to side ventilation, this ven-
tilation method can allow more dirt to enter
the rear area of the refrigerator, which
makes regular maintenance of the gas
burner, at least once a year, necessary.

Side installation with floor-roof ventilation
Side installation
If the appliance is installed on the same side of the vehicle as the entrance
door, it is desirable that the door does not cover the refrigerator’s vents.
If this cannot be avoided there must be a gap of at least 25mm between the
door and the vents.
With this method of installation regular maintenance of the gas burner is only
possible once the device has been dismantled. The refrigerator has to be
installed in a way allowing easy dismantling.

6.1.3
The maximum cooling performance
is not available!
Please assure at all the installation
variations correct ventilation and
extraction, as described in item 6.3!
Fig.4
Fig.5
Rear installation often causes an unfavou-
rable installation arrangement, as ideal
ventilation cannot always be assured (e.g.
the lower ventilation grille is covered by the
bumper or the rear lights of the vehicle!)
(Fig. 4). The maximum cooling performan-
ce of the aggregate is actually not availa-
ble.
Another variant of the rear installation is
the side installation of the ventilation grilles
(fig. 5). The air-heat recirculation is very
restricted which means the heat exchan-
gers (condenser, absorber) cannot be ade-
quately cooled. The variant with an addi-
tional ventilation grille mounted in the floor
also has a bad airflow duct.

Draught-free installation
The refrigerator must be sealed in such a way, that no air from the living area
can get to the gas burner and no draughts counter enter the living aera as well.
Proposal 1:
(Illustrated below are two typical approved methods of sealing.)
Using the Installation Sealing Kit from Dometic
(SP
.No. 241 2559-00, available from Dometic)
Insert lipped seals (A) into the installation recesses
at the bottom and at each side.
Insert deflector plate (B), fitted with a lipped seal (A)
of heavy-duty, non- flammable material, into the
installation recess.
Insert deflector plate (B) in such a way that the hot
air escapes through the air vent grille into the open
air.
Affix the discharge plate to the caravan wall, not to
the refrigerator !
In addition, discharge plate (B) with its lipped seal
(A) must seal the refrigerator off from the living area
(see FIG. 1).
Ensure that the refrigerator is installed level in the
recess.
Proposal 2:
Another option is to provide the refrigerator with a cowl (A).
The cowl (A) should ideally be affixed to the caravan wall,
not to the refrigerator. Insert sealing strips at the bottom
and sides of the cover.
Finally, push the refrigerator into the cover from the front.
Both of these installation options facilitate the remo-
val and installation of the appliance for servicing.
Comment:
Other methods of sealing may be approved. However the
chosen method must prevent draughts entering the living
space of the motorhome. Failure to seal correctly will allow
warm air to collect around the refrigerator and its performance will be affected.
If the cavity between the caravan wall and the refrigerator is sealed so that fumes
cannot penetrate the living area it is possible to vent the flue gas directly through the
upper grille without using the aluminium flue pipe. For this installation method, it is
recommended that the same air vent grille should be used at the top and at the
bottom (L200), and that the T-piece of the flue pipe is turned 45 degrees.
6.2
FIG. 1
WARNING! DO NOT use any easily inflammable materials (in particular sili-
cone sealing agent or similar) for sealing! The device manufacturer's pro-
duct liability and guarantee shall lapse if such materials are used.
20
In this case, for gas operation, do not use the upper winter covering!
If even with draught-free installation a fume chimney is desirable, you must incorpor-
te the L100 ventilation and extraction system into the upper air vent opening
.
Installation of fume chimney: please refer to point “6.7”.
Ventilation and extraction
A correct installation is important for correct operation of the appliance to ensure,
there is no build-up of heat at the back of the appliance. This heat must be allowed
to escape into the open air.
In the event of high ambient temperatures, full performance of the cooling unit
can only be achieved by means of adequate ventilation and extraction.
Ventilation is provided for the unit by means of two apertures in the caravan wall.
Fresh air enters at the bottom, extracts the heat and exits through the upper vent
grille.
The upper ventilation grille should be positioned as high as possible above
condenser (A) .
The lower ventilation grille should be flush with the floor of the vehicle, allowing
any gas leakages (heavier than air) to escape directly into the open air.
If such an arrangement is not possible a hole must be provided under the refrigerator
(not close to the burner) so that any leaking LP gas can escape. This must have an
effictive area of at least 13cm²[2inch²]. It is desirable to fit the hole with wire mesh or
similar, and an angle plate to protect it from stones, mud etc., the wire mesh must not
reduce the effective area of 13cm² [2inch²] .
The ventilation grilles must have an open cross-section of at least 250cm².
This is reached using the Dometic Absorber Ventilation and Air Extraction
System L100 / L 200 that has been tested and approved for this purpose.
Comment:
If the distance between the wall and the refrigerator is greater than 20mm [3/4”] the
gap can be reduced to 20mm [3/4”] by fitting a suitable baffle piece.
6.3
3/4”
Deviations shall require the consent
of the manufacturer.
Correct mounting of the lower ventilation grille facilitates the access to
the electrical and gas connections during maintenance work.
